Locust Swarmadmin

Artifact Hub Docker Image Version (latest semver)

Locust is an easy to use, scriptable and scalable performance testing tool. But it is not very flexible. Specially when it comes to run multiple different configured loadtests in kubernetes cloud.

This project solves this problem by adding a additional admin interface and API to dynamically start Locust instances in your kubernetes cluster.

All configurations are stored on your kubernetes cluster.

Installation on Kubernetes

The Helm installation is based on Deliveryhero's helm charts. (Version 0.20.2)

cd k8s/
helm install -f values.yaml locustswarm . -n locustswarm --create-namespace
helm upgrade -f values.yaml locustswarm .

The results are exported and stored in Prometheus. They can easily be displayed on a grafana board
